serial no. 540,578.

To all whom 'it may concern:

Be it known that l, CARL llTnonsoi-rnmr,

engineer, a citizen of the German Empire,

purifier and some of which are used for introducing the gas to and theothers for dis-v charging it from the purifier,

wing to this arrangement, the thickness of the layers of purifyingmaterial through which the gas to be purified has to pass, can bevaried. Alt the same time it. 1s possible to make puriiiers of anydesired output, as the gasto be purified has merely to travel fromitssupplyy pipe to the discharge pipes which are adjoining it, so thatapparatus of any desired height may he built.

A simple construction easy to attend, is obtained by. branching ofi" thedifferent gas supply conduits from a single chamber and also making themouth pieces of the outlet conduits to open into a single collectingchamber.

Y In order to insure uniformity of action in the various portions of theapparatus with such an arrangement of a number of gas conduits, thecooperation of which in one 'and the same-apparatus corresponds to anumber of purifiers arranged side-by side, it is advisable to providethe different gas supply conduits with indicator devices which indicatethe gas liow in thel conduits.

This can effected in a simple manner byl arranging m the conduits,ad3ustable throttle valves and connecting them to indicating devicesoperated by the pressure in front of, and behind, the throttle valves.As the quantity of gas passing through the conduit for a given size ofcross-section passage arca left free by the throttle valve, depends onthe diiference in the pressures in front of, and behind, the throttlevalves, it is in that way possible to control accurately the working ofthe apparatus in all its parts.

Ait is advisable to maire the gas pipes in the apparatus of louver-likemembers arranged in a roof-like formation, tho roof surfaces-of whichare perforated in such manner that on the one hand they are used assupports for the purifying mass, while on the other hand they allow thegas to pass. The louvers can be arranged in an adjustable manner sothat, by a suitable movement of the same, support can be withdrawn fromi the purifying mass when it is desired to discharge it from theapparatus.

A purifying apparatus constructed in accordance with the aboveprinciples, isA illustrated by way of example in the accompanyingdrawing. f f.

Figure l is la vertical section through the purifier,i11"'the;-directiQn transversely of the gas conduits. Fig. 2 is aportion of the purifier, partly in section and partly in side elevation,in the direction parallel to the gas conduits, and Fig. 3 is adiagrammatic view of the regulating' and indicator" device for differentpipes, branching off from a single supply.

The purifier chamber is surrounded on all sides with Walls. The twofront walls which are at a right angle to the gas conduits arranged inthe purifier, are formed into double Walls. The purilier walls at thegas inlet side, are marked l, 2, While the walls at the outlet side, aremarked 3, 4. The walls 2, 4, form supports for a number of girders 5which, in their turn, support the louvers. The louvers pass through thepurifier chamber from one Wall to the other and are distributed asuinformly as possible in the said space. The louvers which affordsupport to the purifying mass, form canallike hollow spaces in theinterior of the purification mass, which hollow spaces form iues for thegas. vThe louvers are divided into two groups, one group 6 forming withthe supporting plates 7 the supply conduit for the gas, and the othergroup 8 forming with the Support plates 9 outlet conduits for the gas.The louvers are pivoted at their upper ends to projections of thegirders 5,

`while the bottom ends are pivoted by links the rods 12 on the drawingat 14. The vii-ders 14 as well as the girders corresponding to the rods13, are held in the raised position by a supporting device consisting ofcams 15 rotatably mounted ou the girders 14, in connection with theabutlnents 16 secured to the apparatus. The rotatable cams 15 areprovided with eyes 17, 18 in order to release at will the rods 12 or 13in their raised position, so as to enable them to fall down into thelower position, or so as to secure them in their raisedposition.

The lower end oit' the apparatus is provided with corneal outletbranches 19 for the purifying mass, which are held closed by means oflids 2() with closing brackets 2l.

in the construction of the purifier illustrated in the drawing, it hasbeen assumed thatthere is a cellar or pit under the chamber of thepurifier, so that transport trucks can be brought in the cellar or pitunder the openings ot the outlet hoppers 19, for the purpose ofreceiving the pnried mass. For filling thc trucks traveling hopperscould be :ulvantageously used, with an oscillating bottom closingdevice, suoli as indicated in liig. 1 ot the drawing at 22. (iras isadmitted into the intermediate space between the wa'lls l and 2. Fromthesaid space. openings 23 lead to thc hollow spaces under the louverst3. 'lhrottle valves 2t are 'used for closing the openings 2li to agreater or smaller extent. 'lhe gas outlets leading 'from the hollowspaces under the louvers 8, to the intermediate space between the wallsSi, i, arel marked Q5. v The working of the purifying device is asfollowst-Before the purifier is started, it is filled with the purifyingmass. which can be effected from a floor situated above the purifier.rihe purifier is filled with the mass in such manner that under each ofthe louvers t3, 7 is left a. conduit-shaped hollow space, the shape ofwhich on the lower surface is determined by the angle of slope of thcmaterial. After the apparatus has been filled. gas is admitted into thespace between the walls l, Q. l'he gas passing through the openings 23in the wall 2, spreads among the various conduits closed bythe louve-rs(i. iy suitably adjusting or setting the slide valves J-l, the admissionof gas to the conduits corresponding to the louvers (i, can beregulated. ll`rom the inlet conduits arranged under the louvers t, thegas passes through the intermediate spaces between the.

su i )ortjine surfaces 7. into the )uritfinfY t* n l mass, andvpenetrates through the layer of' the mass situated between the supplyconduit, and the outlet' conduits arrangedV all around and closed bythe.'louversv The arrows in Fig. l of the drawing indicate the path ot'the gas. From the outlet eonduits situated under the louvers 8. thepurified gas passes through the openings 25 in the wall 4, into thespace between the walls `l .and 3, and is carried away from that, point.The layer of the purifying mass, through which the gas is to pass, canbe made any desired thickness. A thickness of layer ot about t300 nini.has been found by the applicant to be very suitable.

When it is desired to empty the purifier, the rods 1Q, 13 are moved fromtheir raised position into the lower position, which, as regards thevrods 12, is effected, according to the drawing, by raising the eyes 17and subsequent lowering of the rods. The rotatable supporting plates 15then slide away from the abutnients 16, so that the system of rods 12can sink. the louvers assuming a position such as that 'shown in thedrawing t'or a group of louvers t. Owing to such a rotation or turningof the lonvers, all support is withdrawn from the purifying inass, sothat when the closing devices 21 are, opened, the purifying mass isfreely discharged through the outlet cones 15).

Fig. 3 shows a device for a more accurate control ofi' the flow in theVarious gas supply conduits. It will be seen here, as in Fig. 2, thatthere are provided adjustable throttling valves QG, 16h. 2G mounted inthe supply conduits 2T, 2T", 2T arranged side` by side.
